Exploded drawing


In order to simplify the cabinet construction as far as possible, we have done without the chamfers shown in the photo. If you prefer to include the all-round front chamfer, you will need the following information:

Sat: 10 mm; 30°

First of all, the individual boards are cut to size (refer to cutting list), stuck together (butt jointed) as shown in the drawing and firmly clamped for the duration of the drying time using sash cramps or parcel tape. Once the cabinet has been completely built, the cut-outs are made for the bass tube and terminals using a jig-saw. The last job is the surface treatment, i.e. painting, veneering or adhesive film.

Inner damping

A half of a mat is put into each satellite.

Extract from HiFi Test

"The listening test proved the value of the impressive deep bass qualities ...." "While the satellite speakers provided the necessary crystal-clear mid- to high-range fill-in ...." "The testers at HiFi Test only have one recommendation to make Buy!"

Verdict: very good


Extract from Audio

"A masterly performance - the bass system produced such deep, deep bass attacks with such amazing clarity from its bandpass cabinets that it ended up with no less than 50 points."

Value for money: very good
